I just created a new project and got the MahApps.Metro from nuget. I added this to my App.xaml:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
But I get one error like this for each ResourceDictionary entry:
An error occurred while finding the resource dictionary "pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml".
But the dictionaries are found because when I run the application the styles are being applied to the controls. It seems to be a design time only error.
Is there any way to hide them? I'm also having errors for each MahApps Style property that I have set in my XAMLs. Since it's a big application my Error List always has ~30 errors.
This is really annoying, because the styles are being applied when the applicatino run, so there's nothing wrong. When I have a real error it turns in a hell to find it in the middle of all of these other 'erros'
I have the same error if i don't have checked "Run project code in XAML Designer (if supported)". Maybe it is a problem.

I was using the stable version on nuget and changed to 1.1.3-alpha225 also from nuget. I did that so I could call dialogs through the ViewModel. But now I'm getting this error:
An error occurred while finding the resource dictionary "pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml"
All other dictionaries are ok:
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
The controls is the only one giving error:
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml"
Does anyone know if it changed on the new version or if there's a known bug?
I am attempting to merge in dictionaries from a dependent class library project, but the resource keys can't be found. Note: I am using this Connect bug workaround from Microsoft which is supposed to allow the framework to search deep enough to find the nested resources. This does not appear to be working.
Example of Failure
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/MyApplication.ControlLibrary;component/ResourceDictionaries/ResourceLibrary.xaml" />
<ResourceDictionary>
<Style TargetType="{x:Type Line}" /> <!-- workaround from MS to allow for this -->
<Main:AppBootstrapper x:Key="bootstrapper" /> <!-- CaliburnMicro bootstrapper, unsure if this is relevant -->
</ResourceDictionary>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
Inside ResourceLibrary.xaml
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="DefaultColorTheme.xaml" />
<!-- ...snip... -->
<ResourceDictionary Source="TransitionControl.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
When doing this, it cannot find the resource keys. If I merge each dictionary in manually from that class library, it works fine. This, IMO, begins to defeat the purpose of abstracting resources out to an external assembly.
Example of Success
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/MyApplication.ControlLibrary;component/ResourceDictionaries/DefaultColorTheme.xaml" />
<ResourceDictionary Source="/MyApplication.ControlLibrary;component/ResourceDictionaries/Images.xaml" />
<ResourceDictionary Source="/MyApplication.ControlLibrary;component/ResourceDictionaries/FontIcons.xaml" />
<ResourceDictionary>
<Style TargetType="{x:Type Line}" />
<Main:AppBootstrapper x:Key="bootstrapper" />
</ResourceDictionary>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
Have I placed the dummy implicit style in the wrong place? Something isn't adding up here. Thanks for looking.
I've learned this the hard way by playing around with it for 3 days.
do not make really deep structures. Have a main dictionary that is just using other dictionaries. The app is not supposed to access anything from the others.
But the crucial thing is to reference them in the right order. it wont work if you load a RD where one of it's contents use something from another one that is not already loaded. The order is truly crucial.
Using WPF Inspector will help you a lot since it makes it possible to track everything donw in an WPF app.
I've got a bunch of styles in my app.xaml and they are all being used just fine in my pages within my SL5 app. I'd like to move these styles to multiple resource dictionaries to make it more manageable and consumable.
First I copied a style to a new resource dictionary in the /Styles/ButtonStyles.xaml page in my project... a snippet looks like this:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style x:Key="RegistrationsRolloverImage" TargetType="Button">
<Setter Property="Template">...</Setter>
</Style>
<Style x:Key="FinancialLedgerRolloverImage" TargetType="Button">
<Setter Property="Template">...</Setter>
</Style>
</ResourceDictionary>
Next I added the following to my App.xaml:
<ResourceDictionary x:Key="MergedStyles">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Styles/ButtonStyles.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
It forced me to add a x:key to the ResourceDictionary tag as I kept getting a build error. Now it builds, but the buttons that use the style aren't getting the style. In fact I'm getting a JS error that it can't find a style with the name of the two styles in my resource dictionary. They work just fine if they are in the App.xaml, but not if they are in seperate resource dictionary. I reflected the generated DLL and can see the styles/buttonstyles.xaml in the DLL.
At a loss... and can't figure out what's wrong. Ideas?
Are they within the same project? Try something more like this in your app.xaml;
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/YourResDictionaryContaining.Proj.Name;component/Styles/ButtonStyles.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
I have to do this to have consolidation of resourcedict's stored in one project, and then add that to the app.xaml of each other project to make them available globally. Currently I run about 6 Resource Dicts acros 20 projects in the same solution this way and it works great.
In the full App.xaml sample you want use "local" resources.
But when you have "local" resources and you want to merge a resource directory the systax a little bit different.
Try it like this:
<Application ...>
<Application.Resources>
<ResourceDictionary>
<vm:ViewModelLocator x:Key="Locator" d:IsDataSource="True" />
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Styles/ButtonStyles.xaml" />
</ResourceDictionary.MergedDictionaries>
<Style x:Key="BaseTextBlock" TargetType="TextBlock">
...
</Style>
</ResourceDictionary>
</Application.Resources>
</Application>
My resource merged in App.xaml. but in design mode not found
in Run time it found and work correctly
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Assets/Styles/Main.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
Style="{StaticResource pnlRibbon}" the resource "pnlRibbon" could not be resolved in design time
Use this syntax:
<ResourceDictionary Source="projectName;component/Assets/Styles/Main.xaml" />
it been solved with add this code to the .csproj file
<ApplicationDefinition Include="App.xaml">
<Generator>MSBuild:Compile</Generator>
<SubType>Designer</SubType>
</ApplicationDefinition>
I am using an opensource wpf TreeListView control. The control is a library project with a themes folder in it containing some xaml theme files. In my wpf project, I have got a reference to the control dll and I would like to know how to reference the dll themes in app.xaml. I tried doing something like this but it throws exception saying can't find the treelistview assembly
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/PresentationFramework.Aero;component/themes/Aero.NormalColor.xaml" />
<ResourceDictionary Source="/TreeListView;component/themes/Aero.NormalColor.xaml" />
</ResourceDictionary>
</Application.Resources>
At the moment I have to copy all the theme files in my wpf project locally to make it work like this.
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/PresentationFramework.Aero;component/themes/Aero.NormalColor.xaml" />
<ResourceDictionary Source="themes/aero.normalcolor.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
Is there a way to reference theme files directly in the TreeListView dll like referencing default themes.
Awaiting
Nabeel
I figure it out myself, I was using the wrong assembly file name.
